Finally found my source of ridiculous nitrates

Awesome, and best of luck. I feel your frustration when seeing nitrates turn blood-red. It sucks to see the solution turn bright orange before even shaking and mixing it together.

 

yea after adding bottle 3 its already almost red

 

It took me 4-30G water changes to start seeing a change. You have a large tank too. I would suspect that you may be reading a concentrated part of the "old" water. Try testing it later tonight once you had more turnover in the tank. I also stuck a couple bags of Nitra-Zorb in my sump that helped some.
If you changed 30G, that is roughtly 30% of the water in your 100G tank, so that means ~30% of the nitrates were removed. Let's say you were at 200ppm, you will then be at 140ppm which is still in the red zone. If your tube turned as red as mine did, it may be higher. I am guessing mine was in the 400-500ppm range, just to keep it in perspective my friend.

 

Well its been 4 hours since shange and my water flows im thinking on turning my tank 45x its size per hour and the test results are in nitrate 0

 

Awesome, well done!

 

And I drew back thau sword and slayed the nitrates

 

My nitrates are still red, it's really staring to *P* me off! I am going to get more rock and see if that will help out. Since the tank was a preditory tank, I removed some of the rock and put it into my smaller tank. Looks like I may need to move it back or just buy more.

 

Water chnge did it for me

 

If the de-nitrification process is being fully completed in any health aquarium then NO3 are a must .. Food and fish create it all the time like Phosphates they just are and I run a reactor to control them both so as to never have any to acclimate . saves me lots of time doing water changes . Build yourself a solution the problem as they are continually accumulating with every feeding and fish waste and sand critters dieing .

 

Thanks Tangster, good info. My 150G has been a headache since the paint incident. I am waiting for my RO tubing to build my denitrator, I have everything else already. I should probably make a phosphate reactor as well while I'm at it.
